(The Grio) — Gay rights advocates celebrated Wednesday as the state Legislature voted to legalize civil unions, although some wondered whether the measure that the governor is expected to sign will make it easier or harder to someday win approval of same-sex marriage. The state Senate approved the legislation 32-24, sending it to Gov. Pat Quinn. It passed despite complaints from some senators that civil unions threaten the sanctity of marriage or increase the cost of doing business in Illinois. After Quinn signs the measure, gay and lesbian couples will be able to get official recognition from the state and gain many of the rights that accompany marriage — the power to decide medical treatment for an ailing partner, for instance. Illinois law will continue to limit marriage to one man and woman, and the federal government won’t recognize the civil unions at all.
